The oxbank or" keys are) those of the which. opomio 10mm 0011(l1tl011 ii nun I I man AS th e 1 "H. {L351 ilill" a may me merithe of disks.

the disak chine can be set almost immediately back to vided into ten parts, separated by the teeth '34, and these parts are numbered consecutively from to 9. By using two sets of numbers on the indicator-wheels of the meter and using two rcading-lines I am able upon a machine such as herein shown to quickly and accurately perform the aritlmetical problems of subtraction and multiplieation. I therefore preferably use a series of large numeral characters from 0 to 9, which are the characters that will be used in addition and multi lication, and I also provide another or smel er set of numerals 0 to 9 for the same spaces; but both naughts are on the same space, the larger figures reading away from the operator, the smaller figures toward the operator, so that both the large and small numerals appear upon the same space-in other words, reading upon the meter away from the operator the large numerals appear consecutively 0 to 9, while the small numerals appear consecutively '0, then 9 to 1, as clearly shown inl ig. 8.

The reading-line of the meter when the meter is at initial position will show a line-of the numerals 0, while the next line above it, which will be the other reading-line of the meter, will show a line'of the numerals 9.

One of the reading-lines, preferably the one nearest to the sight of the operator,'is

uses 101' both addition and multiplication,

while the other reading-line, preferably the one to the rear above the first readingiine, is used for both subtraction and division in problems of subtraction and d1- vision we used the set of numerals which are numbered in the opposite direction to which the spools are rotated and which are shown in ti. 1 drawings as the smaller set of -figures reading toward the operator 3 but, if desired, the relative size of these sets of figures could be changed so that the set of figures used in subtraction could be the largest, or, if desired, each set could be of the same size, in which case one set would necessarily beef a dillcrent color from the other set. To do a problem in subtraction, the minuend is first executed upon the meter so that this set of numerical figures numbered in the opposite direction to which the spools are rotated will show upon the subtraction or second reading-line the minuend. Then the primary keys to the amount of the subtrahend are v pros ed. down and. th meter revolved once,

when the remainder appears. In divisionthe dividend is first executed on the met-er, so t show on the second readin -line (the same reading-line as used in subtraction) the dividend with the same set of characters used in subtraction. Then the primary keys corresponding to the divisor are pressed down, and the'meter, having been shifted to the right to the proper position for the divisor to be divided into the higher figures of the dividend, is revolved as many times as thedivisor will go in the numbers on the numerical wheels operated by the teeth of the segments during the revolving of-the meter, and upon a wheel of the indicator is shown the first figure of the remainder. The meter is then shifted one or more places to the left and in a similar manner operated to obtain the next figure of the remainder, except when it has been shifted more than one space, in which case upon the indicator between these two figures would show a naught for each spaceshifted, and again shifted, and so on until the total remainder shows upon the indicator, which will be read in inverse order, and the sum remaining upon the meter being of a lesser sum than the divisor shows the amount left over. In other words, using the second set of numerals (shown upon the drawings as the smaller set) the operation is almost the reverse of the operation used in multiplication.

In the outer side or edge of the disks are two rows of notches in each series ofdisks,"

and these notches 85 85 are to engage the spring-pressed pawl 77, which has its point 7 9 engaging the notch 85 when the disks are in initial position, but which engages the notch 85 of each disk as it is raised by the primary key. This pawl 77 has a spring 80 working against a pin 81, and the pawl is pivoted at the point 84 and has at its forward lower end a pin 78, resting within a recess 87 of the segment 74, and. this segment 74 when it is desired to release the disks and have them returned to original position by the springs 31, operating against the primary keys, is pressed downward by a lever 71, having a slot 72, in which travels a pin 7 3 of the segment 74, so that the segment 74 pushes down the pin 78 and its pawl 77. The pin 78 also travels in the guide-slot 86 in the lower portion of the side wall 66.

Each of the levers 71 are ailixed to a shaft 68, so that they can all be simultaneously op erated by a common lever 69 upon the shaft 68, which lever extends through the front casing 16 and is held in an upward position by the spring 70; butwhexi pressure is applied to its free end the disks are all released. The segments 74 have the slots'7 6 and 83, through which extend the guide-pins 75 and 82.
